HENRY P. RICHARDSON, OF KILLEN, ALABAMA.

HOOP-MACHINE.

Application filed May 22, 1914.

To all whom it may concern: 7

Be it known that I, HENRY P. RICHARD- soN, a citizen of the United States, residing at Killen, in the county of Lauderdale and State of Alabama, have invented certain new and useful Improvements in Hoop-Machines, of which the following is a specification.

This invention relates to hoop machines and has for an object to provide a machine of the class embodying new and improved features of economy, of manufacture and use as well as reliability of action.

A further object of the invention is to provide a machine embodying improved means for holding a split and perhaps crooked hoop pole on a curve as it progresses through the machine and at a point opposite the rotating knife operating to cut the pole at the curve.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings: Figure 1 is a View of the improved hoop machine in side elevation. Fig. 2 is a view of the improved hoop machine in top plan. Fig. 3 is a view of the improved hoop machine in end elevation as indicated by arrow 3 at Figs. 1 and 2. Fig. 4': is a view of the knife or cutter head in side elevation. Fig. 5 is a diametrical sectional view through the cutter head as indicated by line 5-5 of Fig. 4. Fig. 6 is a per spective view of one of the pole guides. Fig. 7 is a perspective view of another one of the pole guides. Fig. 8 is a diagrammatic view showing the curvature of the hoop pole and the position of the cutter head operating thereon.

Like characters of reference designate corresponding parts throughout the several views.

The improved hoop machine which forms the subject matter of this application comprises a frame 10 supporting and journaling an arbor 11 carrying a cutter head 12 and driven in any usual and improved manner as by the employment of the pulley 13.

Mounted beneath the arbor and in parallelism therewith is a shaft 14 driven in any approved manner as by the pulley 15 and carrying a beveled gear 16. A beveled gear 17 intergeared with the gear 16 is carried by Specification of Letters Patent.

Patented Mar. 30, 1915 Serial No. 840,323.

a shaft 18 vertically ournaled in the frame 10 and carrying a Presser roller 19 above the top of the frame and opposite the cutter 12-. Other shafts 20 and 21 are also vertically journaled in the frame 10 in parallelism with the shaft 18 and driven therefrom by means of a sprocket chain 22 connecting the shaft 17 directly with the shaft 20. The shaft 21 is driven from the shaft 20 by means of gears 23 so that all of the several shafts 18, 20 and 21 are driven from the beveled gear 17. The shafts 20 and 21 carry above the frame two coacting draw rollers 24: and 25 similar to the roller 19.

Standing between the presser roller 19 and the outermost roller 21 is a fixed guide 26 which is oblique to the plane in which the cutter 12 rotates and has its outer face directed toward the opening between the two draw rollers; and the base plate 26 of this guide is secured in any suitable manner to the frame. Pivoted on the front bar of said frame at the point 28 is the base plate 27 of guide which rises from one edge of said plate as at 27 and has an overhanging flange 27 as best seen in Fig. 6. In Fig. 8 is diagrammatically shown how this guide 27 is directed generally toward the advance edge of the cutter 12 so that the incoming hoop always is passed between said cutter and the presser roller 19. The pivoting of this guide is to permit it to yield slightly as its spring 29 permits, when a crook or bend in the pole occurs, and the overhanging flange 27 is to prevent the rotation of the cutter from lifting the pole off the guide. A lever 30 is also pivoted to the frame at 31 and adapted to be manually moved against the hoop pole as it progresses through the machine to secure a greater or less amount of bend at the cutter head as occasion may require.

As shown more especially in diagram Fig. 8 the hoop pole 32 is inserted in the machine against the guide 27 and into engagement between the roller 19 and the cutter head 12 and after being cut at the bend as indicated in that figure, passes on as a hoop against the guide 26 between the rollers 24 and 25 which all rotating in the proper direction serve as means for moving the hoop and hoop pole.

The location of the cutter head relative to the path of movement of the hoop pole will be seen more particularly at Fig. 3 in such position that the knives upon the cutter head serve to meet the hoop pole with a shave out rather than a squarecut,

I claim:

In a hoop cutting 'machine, the combina: tion with a cutter rotating in an upright plane, a presser roller standing at one edge of said cutter, and a pair of oppositely rotating draw rollers disposed beyond the presser roller in the direction in which the hoop moves; of a rigid upstanding guide in the. rear of the cutter and, between the presser roller and the draw rollers, a movable gu-izde comprising a base plate pivoted Gayle; of this natent may he obtained for five cents each, by addressing. the Commissioner of rmnn, i

tothe front. barof the frame and a guide '15 proper upstanding from one edge of the plate forward of the cutter and presser roller and turned inward into an overhanging flange, and a spring pressing this movable guide normally toward the presser 20 operating substantially as Witnesses r 7 WILLIAM A.
